MACHINE FOR SURFACE-SEEN@ Viv/ADDING.

SPECFICATIONformng part of Letters Patent No. 598,608, dated February 8,1898. Applicata inea my 12, i897. sel-a1 No. 636,129. (Nomerie.)

To all whom t may concern.:

Be it known that I, GEORGE V. B. CLARK, a citizen of the United States,residing at Valatie, in the county of Columbia and State of New York,have invented new and useful lin-` which by failing to becomesufficiently driedV r in proper time will render the goods blotchy andimperfect in finish.

Revolving brushes have heretofore been employed for effecting the sizingof goods, the tufts of bristles or other resilient material being bentbackward and then by being suddenly released returning to their normalpositions to discharge the sizing upon the goods in the form of spray;but it is found by experience that the sizing' is liable to becomedeposited on the end of the sizing-tank and will there accumulatesufficiently to run down and drop in large splotches upon the surface ofgoods that are passing under said tank, thereby producing an imperfectsurface on the goods. I provide a remedy for this defeet by means of anauxiliary revolving brush, which is arranged to receive drops of sizingthat may fall from the sizing-tank and to remove the accumulation ofsizing from the outer side of the end of the sizing-tank and dischargingthe same in the form of spray onto the underpassing goods, the discharge1 of such spray being projected, preferably, at

oppositely-inclined angles, so that the two cannot coniiict with eachother.

As represented in the accompanying drawings, Figure l is a plan View ofa machine in which my invention is embodied, and Fig. 2 a longitudinalvertical section of Fig. l at the line X X. Y

In said drawings, A designates the frame of the machine,which frame maybe constructed of any suitable material and in any form suited to thepurpose. As shown, said frame consists of side pieces l, which areprovided with journal-bearings 2, 3, and 4 for purposes hereinafter setforth.

B is a tank or trough for containing sizing in a proper state ofliquidity. Said tank is secured between the side pieces of the frame A,and one end of said tank is formed to in cline outwardly, as shown inFig. 2, from the plane of the bottom of the tank. At the upper part ofsaid end an angular edge 6 is for-med for a purpose that will be fullyexplained later herein; but it should be understood that it is notessential that such'edge should form an acute angle to the top of thetank, for a similar effect, but not so efcient, can be produced byforming said edge at a right angle to the top of the tank.

C is a sizing-roller which is arranged to revolve in the sizingcontained in the tank B, and thereby a coating of said sizing is takenup by said roller preparatory to its removal from said roller and itsdistribution on the surface of the goods as they pass through themachine. The sizing roller is preferably made in a hollow cylindricalform of any material that will not corrode or impart color to thesizing, and it is secured to a shaft 7, that is arranged to revolve injournal-bearings 2 of the frame A.

D is a revoluble cylindrical brush attached to a shaft 8, that isarranged to revolve in journal-bearings 3 of the frame A. Thecylindrical surface of the brush D is provided' with resilient bristlesand is arranged in such manner that while in the machine the ends of thebristles will touch against the surface of the sizing-cylinder C, so asto become charged with the sizing from the surface of said cylinder andso that by the rotations of said brush the bristles will be carried intocontact with the edge 6, whereby the bristles will momentarily be bentbackward, and then after the bristles are successively cleared from saidedge their resilience will cause them to spring into their normalpositions, thereby causing the sizing to be forcibly discharged in theform of spray from said brush, which discharge will be delivered in anangular direction, as indicated by dotted lines under the brush 9 onFig. 2. i

G is an endless apron that is carried on drums H, xed on shafts l,arranged to re IOO volve in journal-bearings 4 on the frame A. Saidendless apron is arranged to carry the goods to which the sizing is tobe applied.

Up to the point last described the machine, or the greater part of it,is old and well known, and consequently forms no part of my invention,only in so far as it may form elements of new combinations, and I willnow describe my invention.

Eis a revoluble cylindrical brush that is ancillary to the brush D andis made substantially like the brush D, and it is arranged so that itsbristles will sweep down the surface of the adjacent end of thesizing-tank, thereby removing therefrom all surplus of sizing that mayhave dropped from, or been left by, the revolving brush D in passingfrom the edge 6 of the sizing-tank B, said surplus of sizing beingliable to (and as a rule will) fall from the end of said tank in greatsplotches upon the goods carried on the endless apron G, and therebyproducing damage to the goods in the manner hereinbefore described.After the goods are properly sized they are usually passed through adrying apparatus, (not shown in the dra\vings,) whereby they will bedried before leaving the machine.

What I claim as my invention is- 1. The coinbnatiomwith a sizing-tank,B, a feeding-roller, C, arranged to rotate in said tank, and a revolublebrush, D, provided with resilient bristles which contact with thesurface of said roller and also with an adjacent edge of said tank, ofan auxiliary revoluble brush, E, arranged under the brush D and providedwith resilient bristles which sweep the adjacent end of the tank, as andfor the purpose specified.

2. In a machine for sizing goods, the coinbination of a sizing-tank, B,means-substantially as herein set forthfor primarily spraying the sizingon the underpassing goods, and a revoluble brush, E, arranged near thebottom of said tank but eXteriorly thereto; said brush being providedWith resilient bristles which sweep the adjacent end of said tank andremove therefrom the sizing that has dripped thereon; said brush beingarranged to spray the sizing from the outer side of the tank upon theunderpassing goods, as and for the purpose speciiied.

GEORGE V. B. CLARK.
